Summary Secondary transitory pseudohypoaldosteronism (PHA) appears as a consequence of a tubular renal resistance to aldosterone in children with urinary infections and/or obstructive uropathy. The story of a 4 month-old child who had its second episode of dehydration, hyperkalemia, hyponatremia and metabolic acidosis without congenital suprarenal hyperplasia with normal ACTH, 17-hydroxiprogesterone and cortisol is presented. Urine culture showed Enterobacter and the studies revealed a grade V reflux. The DMSA renal scan showed a hypoplasic left kidney with an overall function of 13%. The secondary PHA was confirmed with elevated levels of renin and aldosterone. Medical and surgical treatment was realized with left nephrectomy with good evolution afterwards and normalization of lab studies
